Should you live in Paris or in France, or planning to visit Paris, you will undoubtedly at some time get on to a Metro or RER train. Not so?

Now, for the first time Citymapper has done a survey of the regularity of Paris’s Metro and RER trains. The RER is the metro trains which serve the Ile de France (Greater Paris).

There are altogether 14 Metro lines, numbered from 1 to 14, and 4 RER lines known as the A,B,C and D lines, each of these having sub-lines numbered from 1 to 4.

Citymapper’s survey which covers the month of October this year (2016) shows that the RER line most often delayed is Line E, while the Metro line which is most often delayed is Line 11.
